Description of problem:

https://github.com/redhat-developer/rhdh-plugins/pull/1266#pullrequestreview-3310848245

The PR introduced two dependencies which I think we should double-check:

@roadiehq/scaffolder-backend-module-utils
Is this really needed? I think its fine to have it, but at the same moment, I think our default template should not depend on this, right?

@ai-zen/node-fetch-event-source
Is there a reason that we use this instead of @microsoft/fetch-event-source?

https://www.npmjs.com/package/@ai-zen/node-fetch-event-source refers https://github.com/ai-zen/node-fetch-event-source which is a 5 year old fork of https://github.com/Azure/fetch-event-source

And actually Backstage is using the one from the microsoft org in @backstage/scaffolder-common directly.

As first step I suggest that we switch to the microsoft dependency.

I guess at the end we could also use ScaffolderClient. I will fork this issue to take a look into this option which would make the plugin more stable against changes in the scaffolder API.
